Bear’s stellar conclusion to her Mongolian-flavored fantasy trilogy (after Range of Ghosts and Shattered Pillars) is a satisfying mix of traditional epic fantasy elements, flavored with original magic and grounded with mundane details that make the fantastic seem entirely possible. As the skies shift, reflecting the mortals in power and their associated gods, forces align to support or challenge wizard al-Sepehr as he wages war in the name of the Scholar-God. Warrior Re Temur and his allies travel to Dragon Lake to rally the opposition with Temur’s declaration of his assumption of the position of Khagan, heir to his grandfather’s empire. Battles are fought on both a personal level and a grand scale, with artifacts of obscure ancient civilizations, spirit animals, magical creatures, and poetry and politics. The conclusion is both untelegraphed and completely appropriate. Bear’s trilogy makes a rich contribution to epic fantasy’s expanding borders of emotion and invention.
